so just driving around today i decided to drive like a maniac.
this is an automatic 05 ls, so i put it in first at a light,
punch it, shift to second, to drive, then when it should shift to fourth,
i hear a click coming from the under-hood fusebox area and my car shuts off.

it started up fine after coasting to the next light in neutral.
first time its ever done anything like that.


any ideas of what exactly happened?
